That's not the only change Beyonce has noticed since announcing her pregnancy at the MTV Video Music Awards in August.

"I feel empowered!" she recently told the Associated Press. "It is the most powerful creation for you to be able to have a life growing inside of you."

The couple has wasted no time prepping for the arrival of their first child. A nanny search is under way, and the pair have already lined up a live-in expert for the first month -- the Grammy winner's mom, Tina Knowles, 57.

Though Beyonce claims she doesn't know the sex of her baby, she has reportedly bought pink Christian Louboutin baby booties. Plus, a source tells the new issue of Us Weekly -- out Friday! -- that the A-list couple has already picked out a name.

Says a source: "Jay told his sister to order a whole wardrobe of baby-girl clothes!"
